Petro says he wants to spend more time following a passion of his – stopping people from being wrongly convicted of crimes. He and his wife wrote a book called False Justice, and Petro says retiring from his job as chancellor will let him accept invitations to speak at law schools about the crime issue.

He tells statehouse correspondent Bill Cohen he’ll soon speak at the University of Pittsburgh, the University of Akron, and even overseas.

Before that job, Petro served as an Ohio legislator, state auditor and state attorney general.
